SAP ABAP Overview

SAP ABAP is the core programming language of SAP systems. It powers business logic inside SAP ERP and SAP S/4HANA. ABAP stands for Advanced Business Application Programming. It works closely with SAP data models. ABAP runs inside the SAP application server. This gives high security and stability.

ABAP supports procedural and object oriented programming. Modern ABAP focuses on clean architecture. Developers use classes, interfaces, and exceptions. ABAP integrates tightly with the ABAP Dictionary. This ensures strong data typing and consistency. Open SQL handles database access. It stays independent from the underlying database. SAP HANA optimizes Open SQL execution.

ABAP supports advanced data modeling through Core Data Services. CDS views push logic to the database. This improves performance. ABAP Managed Database Procedures allow SQLScript execution on HANA. This reduces data transfer.

ABAP also supports SAP Fiori applications. It exposes data using OData services. SAP Gateway manages service communication. ABAP handles validations and authorization checks. This protects sensitive business data.

ABAP supports integration using IDocs, BAPIs, RFC, and REST APIs. It connects SAP with external systems. Modern ABAP also supports cloud development on SAP BTP. The RESTful ABAP Programming Model enables scalable services. SAP ABAP remains critical for enterprise development and digital transformation.

Everything Professionals Can Do With SAP ABAP

Below is a list of everything one can do with SAP ABAP.

1.    Core Application Development With ABAP

ABAP allows professionals to build complete business applications. Developers write executable programs and modular code. These programs handle finance, logistics, sales, and HR flows. ABAP interacts directly with SAP tables and views. It ensures data consistency.

ABAP programs follow event driven execution. The runtime handles memory and database calls. Developers focus on logic.

REPORT z_sales_report.

SELECT vbeln erdat netwr

FROM vbak

INTO TABLE @DATA(lt_vbak)

WHERE erdat >= sy-datum - 30.

This syntax reads sales orders from the database. The system optimizes the query. Professionals tune logic for large datasets.

2.    Data Dictionary and Data Modelling

ABAP professionals design strong data models using the ABAP Dictionary. They define tables, views, and data elements. This ensures consistency across the system. Dictionary objects control storage and validation.

Domains define value ranges. Data elements define semantic meaning. Tables define physical storage.

DATA lv_amount TYPE vbak-netwr.

This line binds program logic to dictionary definitions. It reduces errors. It improves reuse.

3.    Modularization and Reusable Code Design

Professionals create clean and reusable code using modularization. ABAP supports includes, subroutines, function modules, and classes. Modular code improves testing and maintenance.

Function modules support global reuse. Classes support object-oriented design.

CLASS zcl_tax_calc DEFINITION.

  PUBLIC SECTION.

    METHODS calculate_tax

      IMPORTING iv_amount TYPE p

      RETURNING VALUE(rv_tax) TYPE p.

ENDCLASS.

This syntax shows ABAP Objects usage. Professionals prefer classes in modern systems. They follow clean architecture.

4.    Object Oriented Programming in ABAP

Modern ABAP uses object-oriented programming heavily. Professionals design interfaces and classes. They apply inheritance and polymorphism. This improves scalability.

ABAP Objects supports encapsulation. It supports exception handling.

TRY.

    DATA(lo_calc) = NEW zcl_tax_calc( ).

    DATA(lv_tax) = lo_calc->calculate_tax( iv_amount = 1000 ).

  CATCH cx_sy_arithmetic_error.

ENDTRY.

This approach improves stability. It supports enterprise scale development.

5.    Database Performance and Open SQL

ABAP professionals focus strongly on performance. They use Open SQL for database access. Open SQL stays database independent. SAP optimizes it internally. SAP ABAP Certification validates technical expertise and improves career credibility in enterprise environments.

Developers avoid nested selects. They use joins and buffering.

SELECT a~vbeln b~posnr b~netwr

FROM vbak AS a

INNER JOIN vbap AS b

ON a~vbeln = b~vbeln

INTO TABLE @DATA(lt_items).

This syntax improves performance. Professionals analyse execution plans. They reduce load on HANA.

6.    ABAP on SAP HANA

ABAP on HANA changes development style. Professionals push logic to the database. They use CDS views and AMDP. This reduces data transfer.

ABAP Managed Database Procedures use SQLScript.

METHOD get_sales_data BY DATABASE PROCEDURE

FOR HDB LANGUAGE SQLSCRIPT.

  result =

    SELECT vbeln, netwr

    FROM vbak;

ENDMETHOD.

This method runs directly on HANA. It improves speed. Professionals design code for HANA first.

7.    Core Data Services and Data Modelling

CDS views define semantic data models. Professionals use CDS for reporting and APIs. CDS supports annotations. These annotations control UI and authorization.

@AbapCatalog.sqlViewName: 'ZV_SALES'

define view Z_CDS_Sales as select from vbak {

  vbeln,

  erdat,

  netwr

}

CDS views support analytical engines. They integrate with Fiori. They reduce redundant logic.

8.    SAP Fiori and UI Development

ABAP professionals support SAP Fiori development. They expose data using OData services. They connect backend logic to UI5 apps.

SAP Gateway handles OData.

METHOD sales_get_entityset.

  SELECT * FROM vbak

  INTO TABLE et_entityset.

ENDMETHOD.

This service feeds Fiori apps. ABAP ensures secure access. It handles validations.

9.    Integration With External Systems

ABAP supports strong integration. Professionals use IDocs, RFC, BAPI, and REST APIs. This connects SAP with external tools.

Modern ABAP supports HTTP clients and JSON.

DATA(lo_http) = NEW cl_http_client( ).

Professionals handle authentication and payload mapping. They ensure reliability.

10.  Enhancements and User Exits

ABAP professionals extend standard SAP without modification. They use user exits and BAdIs. This protects upgrade safety.

Enhancements add logic at predefined points.

METHOD if_ex_badi_example~execute.

  lv_flag = abap_true.

ENDMETHOD.

This approach follows SAP best practices. It keeps the core clean.

11.  Workflow and Background Processing

ABAP controls background jobs and workflows. Professionals schedule batch programs. They handle large volumes.

ABAP supports event-based workflows.

CALL FUNCTION 'JOB_OPEN'

  EXPORTING jobname = 'Z_DAILY_JOB'.

This allows automation. It supports enterprise operations.

12.  Security and Authorization Handling

Security remains critical. ABAP professionals handle authorization objects. They protect sensitive data.

AUTHORITY-CHECK OBJECT 'V_VBAK_VKO'

ID 'VKORG' FIELD lv_vkorg.

This ensures role-based access. It prevents data leaks.

13.  Testing and Debugging

ABAP provides strong testing tools. Professionals use ABAP Unit for automated tests. They use the new debugger for deep analysis.

CLASS ltcl_test DEFINITION FOR TESTING.

Testing improves quality. It reduces production issues.

14.  ABAP for Cloud and RAP Model

ABAP now supports cloud development. Professionals use the RESTful ABAP Programming Model. RAP supports clean services and behaviour definitions.

define behavior for ZI_Sales

persistent table zsales

lock master

{

  create;

  update;

  delete;

}

This model supports SAP BTP. It ensures future readiness.
